    • Good deal, great desktop computer...
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
I put this iMac into service February, 2018. Even though it was refurbished, it seemed to be in new condition. Everything works and it is much faster than other Macs I have (due to Quad core). The screen is bright and sharp. The Magic Mouse is great. I wish the keyboard had a ten key number pad. I've been back with Mac since 2004 after living in the PC world for almost 20 years. Neither world is perfect, but I enjoy the integration of the Apple eco-system and use it to the fullest with iPhone, iPads, and AppleTV's. The way that family works together is without parallel in the PC world. ======== Update (2 years later): Ultimately I found the internal 1TB HDD to be too slow...bootup took forever...so I took it to my local Apple certified support store and had them swap that out for a 256Gb SSD. It now boots very quickly and seems to have less problems with the OS clean-installed on that SSD. I keep all data on an external Drobo drive so that all that is on the SSD permanently is the OS...which leaves about 185Gb of temp storage space for working space. It also works well for iCloud documents which disappear from the local drive after a period of inactivity with a given document. ========== Update 2 (after 4 years) I have four Macs in operation ranging in dates from 2010 (running El Capitan) to a new M1 MacMini. I do have Big Sur running on this 2015 iMac without problems or stalling issues. Of the four, I think this iMac may be the most dependable and robust of the lot. It is really a good computer (after the SSD upgrade I mentioned above)....maybe the best Mac I've ever owned (and I'm sure I've had at least 10). This is a heqq of a value. ... show more

    • Great machine for those looking to get into Apple
Set: Intel Core i5 | 16 GB RAM | 1 TB HDD
What I like: The screen is fantastic The CPU runs Photoshop really well for my uses Runs well 4 years after it's released Runs programs very well What I disliked: The 1tb hard drive is slow... very slow Lack of expandability in the future Let's get the elephant out of the room, Apple puts slower 5400 rpm drives in their iMacs. If you have the option to get it with an SSD it's worth the investment. Though it may take a bit to load programs like Photoshop, once it does it runs very well and quite smoothly. You can upgrade this later down the line to an SSD, but you must detach the front glass and screen to do so, so find a place that has professionals to do so for you. Reality is though, I knew what I was getting into with the drive, and it just means it may take a few moments to launch Photoshop or Premier Pro. Once it's loaded it doesn't need the drive anymore and I have to say I have been very pleased. I've edited a couple videos on it with effects and transitions that didn't give me any issues, and I edit from attached storage which also helped with the slow drive issues I would have had otherwise. The screen is phenomenal, and the extra resolution is a godsend when editing videos or working on high resolution files. It simply is a great device and I couldn't recommend it enough. ... show more

    • I upgraded by 2009 iMac
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
My early 2009 iMac was still working well, but it was limited in ability to run the newest software. It had a 24 inch screen, so it was a large one. I upgraded to this late 2015 iMac with a 21.5 inch screen. The better resolution on the new Mac makes the smaller size be no problem. It came with El Capitan operating system, the same as on my previous iMac, and I was afraid that I would again be unable to upgrade. However, after transferring all of my files to the new computer, I downloaded and installed Mojave. Man, it works well! Faster than my 2009 iMac and with new abilities. I don't know why the refurbisher did not install the newer operating system (2 steps up); it is free. One thing I had to adjust to: I used Excel on my old Mac. It was an early version of the spreadsheet, bought when I did not have to have a subscription to use it. I was happy with it. However, with the new iMac I am unable to use the Excel spreadsheet except for read-only. The same is undoubtedly true for Word, although I haven't tried it. (Somehow Microsoft knows when you change machines and try to transfer Excel to the new one. I use a spreadsheet for only 1-2 hours per week, and I refuse to pay Microsoft $60 a year to use it. So I opened the 8-10 Excel spreadsheets into Numbers (Apple's answer to Excel). Some things are different, especially graphs (which Numbers calls "charts"), but I have been able to to everything with Numbers that I did with Excel--and Numbers comes free with Mac. I can even export a Numbers 'sheet as an Excel spreadsheet for my few Windows friends. I have used Apple's Pages rather than Word for some time, so that is no problem. The computer came with the small Apple keyboard and mouse. I had a large keyboard with a number pad, and I will continue to use it. I do like the Apple mouse, however, and am using it. Needless to say, I am extremely happy with my iMac, as I have been with all things Apple. ... show more

    • 5400 Speed Spinning Hard Drive
Set: Intel Core i5 | 8 GB RAM | 1 TB HDD
Nice for the money, purchased for my Kid's Covid-19 stay at home learning. Great having a workstation vs. laptop for them. A few things on this specific model, the HD is extremely slow as compared to today's SSD's. Longer Loading times, and seek times are to be expected vs. Near instant loading on newer computers. I ended up purchasing a USB External SSD drive and booting/loading from that vs. the internal hard drive. I stuck it on with a command strip. It now runs great. Bootup time went from 2-3 minutes to less than a minute. Application loading is improved as well. Good buy. ... show more
